[size=+3]Sofirn 21700 5000mAh (Black)[/size]
Official specifications:
A high capacity 21700 from Sofirn.
The two cells match nicely and have a build in fuse that I blew on both batteries, one at 30A and one at 20A.
Some test is missing due to the blown fuse in the cells.
[size=+3]Conclusion[/size]
The batteries looks like good batteries, but be careful with overloading them, the protection will disable the cell permanently (This is, of course, better than risking a battery explosion).
[size=+3]Notes and links[/size]
The batteries was supplied by Sofirn for review.
